Privacy Policy
Last updated: October 3, 2026
This policy explains what data whenera (the “service”) collects, why, and how you can manage it.
Contact
Questions about your data and deletion requests: support@whenera.com or the feedback form.
What we collect
- Account: email, nickname, password hash (the password itself is never stored), avatar. With Google sign-in — your Google account id, email and profile picture.
- Guest identifier: the `hg_guest` cookie (up to 1 year) — keeps your progress, streaks and card history before you register.
- Gameplay: sessions played, answers, scores, completion times, likes, collection, packs you create.
- Feedback: your message, the reply email (if you leave one) and technical context — page, language, viewport, last game.
- Visits: pages viewed (path with query string and referrer), a per-visit id — aggregated under your account or guest token.
- Technical data: session and language cookies, theme preference in localStorage; your IP address is processed for abuse protection (rate limiting).
Why we need it
- running the service: progress, streaks, leaderboards, the Daily Cup;
- carrying guest progress into your account when you register;
- in-service notifications;
- product analytics — which modes get played and where people drop off, to improve the game;
- moderating user content and preventing abuse.
Legal bases
Consent given at registration (the checkbox accepting the Terms and personal-data processing); performance of the Terms of Use (your game progress); legitimate interest — product statistics and service security.
Cookies and local storage
Only first-party functional cookies are used: `hg_guest` (guest progress, 1 year), the account session (30 days), `lang` (interface language). Local storage holds theme, completed tutorials and settings.
No advertising cookies or third-party trackers — all analytics runs on our own infrastructure and never leaves the server.
Who receives data
Data is never sold or shared with ad networks. Processors: the server and database hosting provider; Google — only if you sign in with a Google account.
Card images load from external sites (Wikimedia Commons, museum and archive websites): fetching them exposes your IP address and referrer to those sites — the same as visiting them directly.
Retention
- account — until you delete it;
- guest token and linked sessions — up to ~1 year of inactivity;
- the analytics event stream — 90 days;
- feedback submissions — up to ~1 year;
- database backups — limited time under the backup schedule.
Your rights
- view and fix your data in your account;
- request an export or deletion of your account and related data — write to support@whenera.com from your account address;
- withdraw consent by deleting your account (processing before withdrawal stays lawful);
- complain to your local data-protection authority.
Children
The service is not directed at children under 13 and does not knowingly collect their data. If we learn of an account belonging to a child under 13, we will delete it.
Changes to this policy
The current version always lives on this page. Material changes will be announced with an in-service notification.
